Small part of a program : d and c versions performances diff.

[Larry via Digitalmars-d-learn]

Yes you are perfectly right but our need is to run the fastest 
code on the lowest powered machines. Not servers but embedded 
systems.

That is why I just test the overall structures.

The rest of the code is numerical so it will not change by much 
the fact that d cannot get back the huge launching time. At the 
microsecond level(even nano) it counts because of electrical 
consumption, size of hardware, heat and so on.

It is definitely not something most care about and i cannot 
disclose the full code for license reasons (yeah I know I suck 
and generate some fuss for nothing but.. I just execute.)

But D may be of our use for non critical code to replace some 
Python there and there. It is definitely a good piece of 
engineering. And it will help save money.
